title: Pain treatment in post-traumatic hip fracture in the elderly: regional block vs. systemic non-steroidal analgesics.
abstract: BACKGROUND
  This prospective, randomized double-blind study, conducted over 19 months in a tertiary care ED, sought to determine if a fascia-iliaca regional anesthetic block provides better and safer pain relief than does parenteral analgesia.
  
  
  OBJECTIVE
  This study also aimed to determine the effectiveness of parenteral NSAID analgesia for acute hip fractures.
  
  
  METHODS
  Patients >65 years old presenting at an adult ED with acute hip fractures were randomized upon presentation to the ED into two groups (A and B) using numbers generated by the EPI-INFO™ (Atlanta, GA: Centers for Disease Control and Prevention) program. The randomization list was kept by one of the authors who did not interact with the patients. Two groups of patients were to receive either (A) a fascia-iliaca block with bupivacaine and parenteral saline injection, or (B) the same block with saline and an IV NSAID injection. Upon admission to the study, vital signs such as blood pressure, mean blood pressure (MAP), heart rate (HR), respiratory rate (RR) and pain-intensity measurements [using the Visual Analogue Scale (VAS)] were obtained and repeated at 15 min, 2 h and at8 h. The occurrence of complications was registered.
  
  
  RESULTS
  One hundred seventy-five patients were randomized, and 21 were excluded from participation. The remaining 154 patients were grouped as: group A (n = 62) or group B (n = 92). The mean pain level on admission to the ED for all patients, assessed with the VAS, was 8.21 ± 0.91 (CI 95%: 6.43-9.99); in group A the VAS was 7.6 ± 0.22 and in group B 8.5 ± 0.72 (p = 0.411). At 15-min evaluation, values were: group A 6.24 ± 0.17 and group B 2.9 ± 0.16 (p < 0.001). At the 2-h assessment, values were: group A 1.78 ± 0.11 and group B 2.3 ± 1.16 (p = 0.764). At 8 h the VAS for group A was 2.03 ± 0.12 and for group B 4.4 ± 0.91 (p = 0.083).
  
  
  CONCLUSIONS
  THIS STUDY DEMONSTRATES THAT: (1) parenteral NSAIDs are very effective as analgesics after hip fractures in elderly patients, (2) fascia-iliaca regional blocks are nearly as effective for up to about 8 h after administration and (3) regional fascia-iliaca blocks effectively control post-hip fracture pain. (4) Fascia iliaca regional block has a rapid onset.
